Combining split-out instruments

[Philip Harris via LilyPond user discussion]

Hi










I have created quite a big example as I am still learning!



Of the back of my example I have a few questions...



2) How do I make the rests smaller (#'mensural does not seem to work)







Thanks

Phil

I'm trying to create a teaching page for samba "grooves" for non-music readers !! Each groove is typically about 4 measures long and each instrument plays up to 4 notes per measure (the tune is made up from multiple repetitions of these grooves!) I want to use the same note definitions in multiple scores in the .ly file so I can have each instrument separately (possibly with a mnemonic) and also together on one stave - so you can more easily see where the the notes are played in relation to the other instruments - I hope my attached .pdf file gives an insight In it I use bassdrum (bd) for my "pulse" and  cowbell (cb) for the tamborim - as I cannot find these actual instruments in the midi voices 1) how do I define a set of notes for each of two instruments such that I can use them alone and with eachother (I don't want to see rests and notes on the same vertical line) 3) How do I extend the bar lines so they span all the scores (like the initial one does!) 4) Do I have to use other instruments to simulate samba instruments (it would be nice to be able to generate midi and play the combined and individual parts I have other questions - but I suspect I might be going about this in the wrong way - so feel free to point out how I might want to do this "properly" :-)
